To make a world history, you could follow these steps: Research and gather information on major historical events, people, and societies from different parts of the world and different time periods. Organize the information chronologically and by region or civilization. Write a narrative that connects the events and describes their significance and impact on world history. Include primary sources such as texts, artwork, and artifacts whenever possible to add depth and context to your history. Verify the accuracy of your information with multiple sources and consider different perspectives on the events you are describing. Revise and edit your work to ensure clarity and coherence. Keep in mind that world history is a vast and complex subject and it is impossible to cover everything in one piece of work. Therefore you should be selective of the events and topics you choose to include in your history and focus on the most important and significant ones.

These gates can be combined to form more complex circuits, such as the NOT gate (also known as an inverter), the NAND gate, and the NOR gate. Other types of gates, such as the XOR (exclusive OR) gate and the XNOR (exclusive NOR) gate, can also be built using combinations of AND and OR gates.

Military drones are typically launched from a runway or a mobile launcher, and are controlled remotely by operators using a ground control station. The operator uses the station to control the drone's flight, navigation, and payload. If drones were available commercially, the cost of operating them would depend on a variety of factors, such as the type of drone, its payload, and the cost of the required ground support equipment. Additionally, the cost of operating a drone would include expenses such as fuel, maintenance, and insurance. Without knowing the specifics of the drone and its intended use, it is difficult to provide an estimate of the operating costs.

It is not currently possible to make a machine that can see the future with certainty. Predictive modeling, which uses statistical techniques and machine learning algorithms to make predictions about future events, is a rapidly advancing field, but it is based on patterns and trends in past data, and is therefore limited by the quality and quantity of that data. Even the most accurate predictive models are subject to a degree of uncertainty, and can only provide probabilistic predictions. Additionally, many factors that can affect the future, such as human behavior and natural events, are inherently unpredictable.

Building a "time machine" would likely require a significant amount of advanced technology, such as a stable and powerful source of energy, an understanding of the laws of physics and specifically, general relativity, and the ability to manipulate and control space-time. One proposed method for building a time machine is through the use of a "wormhole," a tunnel-like structure that connects two distant points in space-time. The idea is that one end of the wormhole could be moved through time, while the other end remains stationary, allowing an object or person to travel through the wormhole and move through time. However, the creation of stable wormholes and the manipulation of space-time on such a scale remains purely hypothetical and currently beyond our current scientific understanding and technological capabilities.

  Zero (0) was first invented by the ancient Babylonians and later adopted by the ancient Egyptians. However, the modern concept of zero as a number that represents nothing was developed by the ancient Indian mathematician Brahmagupta in the 7th century. He was the first to write down the rules for arithmetic with zero, such as the fact that 0 times any number is equal to 0, and that you cannot divide by zero. The modern symbol for zero (0) was first used in print in a book called "Arithmetica Integra" by the mathematician Johann Kepler in 1623.
